(OIL, COAL, NUCLEAR POWER) • AND WHO WILL GET THEM-WHO WILL GET TO USE THE GOODS PRODUCED? (RICH, MIDDLE CLASS, POOR)

  8. II. THE FUNDAMENTAL PROBLEM THAT ALL SOCIETIES FACE B. SOCIETIES HAVE USED THREE WAYS TO ANSWER THOSE QUESTIONS • MARKET ECONOMIES-SUPPLY AND DEMAND DETERMINE THE PRICES OF GOODS • COMMAND ECONOMIES-THE GOVERNMENT MAKES ALL DECISIONS ABOUT DISTRIBUTION AND PRODUCTION • MIXED ECONOMICS-A MIXTURE OF THE TWO ( ALL COUNTRIES ARE A MIXTURE, EVEN US)
